Abstract

A bed and wheelchair arrangement is disclosed in which a center portion of the bed includes, or is attachable to, apparatus for forming a chair on wheels. The center section of the bed mattress is hinged so that it can be bent to form a chair seat and back. In one embodiment, a support portion for the center mattress section is hinged to support the mattress in the chair configuration. In another embodiment, the carrier structure swings through the bed structure.

Claims

1. An apparatus for facilitating the transfer of a person from a bed to a wheelchair comprising the combination of

a bed having

an integral frame extending the entire length of said bed and having head, foot and center sections,

a mattress having head and foot portions supported by said head and foot sections of said frame, respectively, and a center portion, and

carrying means for supporting said center portion removably supported on said center section of said frame;

at least said center portion being bendable along a line substantially parallel with the longitudinal centerline of the bed so that a section thereof on one side of the line can be pivoted upwardly into the position of a chair-like back support for the person while the other section thereof serves as a seat; and

wheeled carriage means operatively associated with said carrying means and said center portion for supporting and laterally extracting said center portion and carrying means as a unit from the remainder of the bed to serve as a wheelchair.

2. An apparatus according to claim 1 wherein said carrying means includes

lockable hinge means having a pivot axis along said line for locking the upwardly pivoted section thereof in its chain-like back support position.

3. An apparatus according to claim 2 wherein said carrying means includes first and second substantially parallel tubular members extending transversely of said bed adjacent the longitudinally spaced edges of said center portion,

and said carriage means includes two arms insertable into said tubular members.

4. An apparatus according to claim 2 wherein said carriage means is fixedly attached to said carrying means and includes means for raising and lowering the wheels thereof.

5. An apparatus according to claim 1 wherein said carrying means includes first and second substantially parallel tubular members extending transversely of said bed adjacent the longitudinally spaced edges of said center portion,

and said carriage means includes two arms insertable into said tubular members.

6. An apparatus according to claim 5 and further comprising

means connectable between said arms and the upwardly pivotable section of said carrying means for maintaining said section in said chair-like back support position.

7. An apparatus according to claim 1 wherein said carriage means is fixedly attached to said carrying means and includes means for raising and lowering the wheels thereof.

8. An apparatus according to claim 1, wherein said carriage means includes coupling means for detachably securing said carriage means to said carrying means.
